homepage Round-Robin the src hash value of iframe. Once it is found that it has changed, hash is used to obtain the required information.The implementation of this method is complex and has limited functions. In IE and FireFox, the URL length can be about 2000 characters. It may be enough for a common requirement. Unfortunately, it is far from enough to transmit a large amount of data.

device.Therefore, an IRP may be forwarded multiple times. In order to record the operation of an IRP in each layer of equipment, the IRP will have an array of io_stack_location (stacks, positions). The number of elements in the array should be greater than the number of devices traversed by the IRP. Each io_stack_location element records the actions that are made in the corresponding device. For the corresponding io_stack_location of this layer device, it can be obtained by iogetcurrentirpstack
